Abstract

An unmanned autonomous vehicle for substantially lateral displacement of feed lying on a ground, comprising two wheels separately drivable by separate drive units, a torque difference adjusting device for adjusting the torque difference between the wheels, a control unit for controlling the vehicle and moving it in a direction of travel by controlling at least one of the separate drive units, a feed displacing device for substantially lateral displacement of the feed, and an adjusting device which is arranged to adjust the height and/or the position of a lowest point of the feed displacing device. The adjusting device comprises a vehicle tilting device which is arranged in such a manner that the lowest point will be located at least substantially off the center line of the vehicle.

Claims

2-1. The unmanned vehicle according to claim 1, further comprising an additional supporting point for supporting the vehicle.

18. An unmanned autonomous vehicle for displacement of feed, comprising:

at least two wheels and at least two drive units for separately driving the wheels;

a control unit for controlling at least one of the drive units to move the vehicle in a direction of travel;

an adjustable feed displacing device for displacing the feed at least laterally to the direction of travel, the feed displacing device being tiltable to have a single lowest point; and

an adjusting device adapted to tilt the vehicle to adjust the feed displacing device so that the lowest point of the feed displacing device is positioned at a point not on the center line of the vehicle.

19. The unmanned vehicle according to claim 18, further comprising an additional supporting point for supporting the vehicle, and wherein the adjusting device adjusts the height of at least one of the wheels or the additional supporting point.

20. The unmanned vehicle according to claim 18, wherein the adjusting device is arranged for automatic adjustment to adjust the feed displacing device to exert a substantially constant pressure on the ground.
